  2. A subclavian catheter is patent and a chest X-ray is done to confirm placement
  3. Arm restraints should be in place during the catheter insertion
  4. An antecubital IV catheter is started and a baseline chemistry profile has been done
Explanation
Answer - B - A measure that is essential is that a subclavian catheter is patent and a chest X-ray is done to confirm placement. TPN administration requires central vascular access into a high-flow vein. Before initiation of the TPN solution, the placement of the catheter tip must be confirmed by a chest X-ray.
